The Harmonized System Nomenclature forms the basis of customs tariffs for about 95 per cent of the world’s countries.
The current review, which will result in the Seventh Edition of the Nomenclature, has been completed and it will enter into force on and from 1st January 2022.
The Harmonized System Nomenclature contains about 5,300 product description codes called headings (constituting some 1,240 codes) and subheadings. The latest review contains about 350 sets of amendments. Not all of the amendments will result in additional codes - some will replace current codes, while others relate to the deletions of codes.
In addition to reflecting trading patterns and product technology, the previous two reviews have included the recognition of products that have been of environmental and social concern. The Seventh Edition of the Nomenclature continues this trend.
